A grandmother and her two granddaughters have a good Samaritan to thank for their safe rescue after they drove into a swimming pool.

The scary incident happened on Tuesday afternoon in Yorba Linda, Calif. Neighbor Anita Campbell heard what sounded like an explosion and children crying, and she took action.

She found a car with the 66-year-old grandmother and her two grandchildren, ages 6 and 9, submerged in her neighbor’s pool. The driver had apparently lost control while driving down a hill, crashed through a brick wall and landed in the water.

“I couldn’t get the doors open in the car. Luckily, the two windows on the passenger side were open. I had the girls unbuckle and come out to me,” Campbell told local station KCAL9. Then she got the grandmother to also get out through a window.

“It was just timing. I just felt I needed to get them out of the car as fast as I could,” Campbell added.

The three victims were taken to the hospital and reported to be in stable condition.
